FREQUENTLY ASKED QUESTIONS
Rapid Set DOT Cement is a specially formulated blend of Rapid Set Cement and high performance additives. Rapid Set DOT Cement is formulated for long life in freeze-thaw regions.
Mix DOT Cement with washed concrete sand and stone (ASTM C33 grade) at a 1-2-2 ratio to produce a durable concrete. Working time is approximately 20 minutes at 70°F.
No. The high-performance properties come from the Rapid Set Cement in the mix.
DOT Cement concrete can be applied from 1/2" to 24" in the 1-2-2 ratio washed concrete, sand and stone concrete mix design.
Water cure all DOT Cement concrete installations by keeping exposed surfaces wet for a minimum of 1 hour. Begin curing as soon as the surface starts to lose its moist sheen. When experiencing extended setting time due to cold temperature or the use of retarder, longer curing times may be required. The objective of water curing shall be to maintain a continuously wet surface until the product has achieved sufficient strength.
Environmental and material temperatures below 70°F (21°C) may delay setting time and reduce the rate of strength gain. Lower temperatures will have a more pronounced effect. Thinner sections will be more significantly affected. To compensate for cold temperatures, keep material warm, use heated mix water. Environmental and material temperatures above 70°F (21°C) may speed setting time and increase the rate of strength gain. Higher temperatures will have a more pronounced effect. To compensate for warm temperatures, keep material cool, use chilled mix water, pre-wet substrate (saturated surface dry). The use of Rapid Set SET Control retarding admixture from the Rapid Set Concrete Pharmacy will help offset the effects of high temperatures.
Yes. The color of Rapid Set Cement can be easily changed using dry and liquid powder pigments designed for use in cement mixes. Due to the lighter color of Rapid Set, the resulting colors are often more vibrant.
